About
At Hermes O., a Naples concierge internist brings more than three decades of Florida practice to a small, relationship-focused panel. Dr. Hermes Koop launched the practice in 2009 after years in both solo and group settings. His guiding philosophy centers on healthy living today, disease prevention for the future, and thorough treatment when illness arrives. Dr. Koop follows his patients across every care setting, including the office, hospital, rehabilitation facilities, and nursing homes. He also makes house calls. He stays directly reachable by telephone 24 hours a day. The practice places strong emphasis on preventive health and nutrition counseling. In-office fingerstick PT/INR monitoring lets Dr. Koop adjust warfarin doses before patients leave. A network of four trusted concierge colleagues covers for him when he travels, so patients always have a familiar level of care available.
